One of the most important aspects of precision reloading is setting the shoulder bump during the full-length (FL) sizing process. You want the amount of “bump” to be precise and identical for every loaded round. However, when you switch brands of brass you may need to change the die position to get the desired bump and case body sizing. And even with the same brand of brass, you may find that you need to adjust your FL die as the number of brass load cycles increases. Brass that has been fired many times will behave differently than new or near-new brass.

Also, even with the same cartridge type, brass loaded for a semi-auto rifle may need more bump than brass fired in a bolt gun. For example, with .223 Rem ammo, you’ll normally want to push the shoulder back farther if the ammo will be shot in a AR15 as opposed to a bolt-action rig.

So how do you make all these needed adjustments for your full-length dies? You can move a conventional locking ring up and down, but that can be a tedious, trial-and-error process. Some guys use shims in one-thousandth intervals, but that still requires taking your dies in and out of the press. Well there is a better way now…

PMA Tool Micro-Die Adjuster

Wouldn’t it be great if you could precisely adjust your FL die up and down in half-thousandth increments, with a simple indexed click. That is now possible with products offered by PMA Tool and Whidden Gunworks. PMA Tool offers a Micro-Die Adjuster that replaces your existing lock ring and can be used with nearly any 7/8-14 full length sizing die. The engraved marks correspond to approximately .001″ of shoulder bump adjustment. Splitting the engraved marks is therefore approximately equal to .0005″ (half a thousandth). Users love this product, saying it adds precision and saves time.

“There has become a need for an easier way to adjust the sizer die properly. Until now there have been few options other than trial and error to get the shoulder setback correct. Anyone who has done this can attest that it’s a slow and imprecise job! Our die and lock ring work together to give the user a clicking feel to the adjustment. Each click moves the shoulder bump .001” so you can easily find the exact shoulder bump that you desire.” — John Whidden

The 2018 Western CMP Cup and CMP Games Event kicked off today at the Ben Avery Range in Phoenix, Arizona. The event runs through Monday, October 22, 2018. For 2018 the CMP takes over what were the Creedmoor Cup Matches, and all matches will now follow CMP High Power Rifle Competition Rules. Notably, this year the Cup and Games matches on the High Power range will be fired on the CMP’s electronic targets. That means less time in the pits, and faster cyeling of relay. Also new this year, the CMP will be adding more smallbore events at Ben Avery. Click HERE for full schedule of events.

The CMP Cup Matches include two CMP 1000 Aggregate Matches followed by a 4-Man Team Match and an EIC Service Rifle Match. Following the CMP Cup Matches will be the CMP Games Matches, which will include Small Arms Firing School (SAFS), Garand/Springfield/Vintage/Modern Military Matches, Carbine Match, Rimfire Sporter match and Vintage Sniper Team Match.

In past years, Dennis DeMille, former Creedmoor Sports General Manager, served as an instructor for the Small Arms Firing School at the Western Games. Below, Dennis shows a young competitor at the CMP Western Games how to adjust his leather sling.

Sling Shooting Tip — The Benefits of Leather
“Many shooters shy away from using a leather sling because they have never been taught how to use one. That’s unfortunate. A leather sling offers more support than a web sling, which is important when competing with the heavier than normal rifles.” — Dennis DeMille

The Benefits of Dry-Fire Training
Once you set up your sling properly, you’ll need practice. Dennis DeMille stresses the importance of dry-fire practice with sling and shooting coat. Dry-Fire training is essential to the sling disciplines. DeMille, a past National Service Rifle Champion, told us that, for every minute he spent in actual competition, he would spend hours practicing without ammunition. While in the USMC, Dennis would practice in the barracks, working on his hold and dry-firing:

“The most important thing is to spend time off the range practicing. Most of what I learned as a High Power shooter I learned without ammunition — just spending time dry firing and doing holding exercises. Holding exercises will really identify the weak parts of your position. The primary purpose of dry firing is to get you used to shooting an empty rifle. If you can shoot a loaded rifle the same way you shoot an empty rifle then eventually you will become a High Master.”

High-Tech Rimfire Rigs
If you watched the smallbore position and prone shooters at the 2016 Brazil Olympic Games, you couldn’t help but notice the exotic rifles competitors were shooting. There were wood stocks, metal stocks, factory-built rifles and customized specials. Why are there are so many different design features and stock types? To answer this question, the NRAblog’s editors called on Jessie McClain of the NRA Competitive Shooting Division.

“The customized rifles, like the Anschütz you showed me, can make a real difference in a shooter’s performance,” explained McClain. “I went from a decent shooter to making the varsity shooting team my freshman year because of the rifle.” As Jessie explained, one new feature out there is the adjustable stock, which she called the Porsche of the shooting world. Fully adjustable from the butt plate to the check piece to the hand stop and risers and bolt knobs, this component is fully customizable to the athlete … which can be a huge advantage. “Every person is different … a customizable rifle fits anyone. A rifle team can purchase four of these and field a shooting team for years.”

The Modern Anschütz Position Rifle
Smallbore match rifle makers are using modern materials in response to the need for greater adjustability (and enhanced accuracy). One of the popular new designs is the Anschütz model 1913 position rifle with a “1918 ALU Precise” brushed aluminum stock. This looks like it has been crafted in an aircraft plant.
